BACKGROUND Early peritoneal recurrence of gastric carcinoma following curative resection remains a great challenge in the treatment and prevention of this disease. AIM To analyze the relationship between levels of tumor markers, carcinoembryonic antigen (CEA) and CA 19-9 in the sera and peritoneal washing, and anatomopathological aspects of the gastric(More)
INTRODUCTION Ectopic hepatic tissue is due to an uncommon failure of embryological liver development that is rarely described in the world medical literature. The incidence of ectopic liver (EL) has been reported to be anywhere from 0.24% to 0.47% as diagnosed at laparotomy or laparoscopy. We describe a case of EL adherent to the gallbladder, removed at(More)
OBJECTIVE The main objectives of this study were to identify, by immunohistochemistry, possible micrometastasis in the regional lymph nodes previously considered free by conventional histopathological examination, and to assess their influence on the survival of patients with colorectal cancer that had been extirpated in a radical manner. PATIENTS AND(More)
AIM To prospectively explore the role of carcinoembryonic antigen (CEA) in gallbladder bile in patients with colorectal carcinoma and the morphological and clinical features of neoplasia and the occurrence of hepatic metastases. METHODS CEA levels in the gallbladder and peripheral blood were studied in 44 patients with colorectal carcinoma and 10 patients(More)
Necrosis of the stomach after isolated splenectomy with the formation of gastrocutaneous fistula is a rare event that occurs in less than 1% of splenectomies. It is more frequent when the removal of the spleen is done because of hematological diseases. Its mortality index can reach 60% and its pathogenesis is controversial, as it may be attributed both to(More)
BACKGROUND Retroperitoneal lipoma is an extremely rare neoplasm. AIMS The authors report a case of giant retroperitoneal lipoma in a 32-year-old white female, with a history of pain and an abdominal mass over a 2-year period. Total abdominal ultrasonography and barium enema showed a large mass located in the retroperitoneal space behind the ascending(More)
CONTEXT The serum carcinoembryonic antigen (CEA) is an important prognostic factor in colorectal cancer, however the rectum presents different routes of venous drainage, stating that the level of CEA in peripheral and mesenteric rectal tumors may be different, depending on the location of the tumor in the rectal segment. OBJECTIVE The goal of this study(More)
BACKGROUND The impact on quality of life attributed to treatment for rectal cancer remains high. Deterioration of the urinary function is a relevant complication within that context. OBJECTIVE To detect the presence of urinary dysfunction and its risk factors among individuals underwent surgical treatment for rectal cancer. METHODS The present(More)
PURPOSE To evaluate the effectiveness of the biliopancreatic diversion surgery with duodenojejunal exclusion in combination with truncal vagotomy in type 2 diabetes mellitus (T2DM) patients with overweight or class I or II obesity. METHODS The study included ten patients with T2DM and class I or II obesity or overweight who were subjected to(More)
OBJECTIVE To evaluate the destruction complex of beta-catenin by the expression of the proteins beta-catetenin, adenomatous polyposis coli, GSK3β, axin and ubiquitin in colorectal carcinoma and colonic adenoma. METHODS Tissue samples from 64 patients with colorectal carcinoma and 53 patients with colonic adenoma were analyzed. Tissue microarray blocks and(More)
